A dramatic case of occlusion of the right pulmonary artery is presented. The diagnosis was clearly established by means of a lung scan and a radionuclide pulmonary angiogram. The entire course of the disease process was followed by radionuclide studies with a gradual but persistent return to normal. Due to the preciseness of the evidence presented, contrast angiography was not.thought necessary.

An irreversible change of the pulmonary perfusion was observed in a series of 100 chronic obstructive pulmonary disease patients studied with a pulmonary artery perfusion scan (PAPS). This perfusion involvement was greater in patients in whom the major respiratory component was pulmonary emphysema as opposed to either chronic bronchitis or bronchial asthma. A statistically significant correlati...

Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst (often in the liver) into the venous circulation. We report a case of hydatid pulmonary embolism following rupture of a hydatic cyst in the right ventricle. Pulmonary angiography showed right pulmonary occlusion. Echocardiography, computed tomography s...

As freon is limited in its use as a generator for aerosol inhalation, powder particles are used as an alternative for inhalation therapy. The pulmonary deposition and clearance of inhaled powder particles was studied by positron emission tomography (PET) in ten patients with chronic obstructive pulmonary disease (COPD) and in five normal controls. The powder, 5 microm in mean diameter, was wate...

background: hydatid disease is a major world health problem and pulmonary hydatidosis is a widespread disease. it is presented with different clinical manifestations. in order to determine the most clinical manifestation, diagnostic methods and clinical outcome in our patients, we conducted this study. methods : forty-nine patients with pulmonary hydatid cysts who were admitted to our hospital ...

UNLABELLED We performed Ventilation/Perfusion scans for patients planned for thoracotomy with resection of the primary or metastatic lung tumors. We predicted the post-operative FEV1 (Forced Expiratory Volume in first second) using Differential Lung Analysis software. METHODS 34 patients were evaluated with Ventilation/Perfusion (V/Q) scans. Ventilation scan was performed with Tc-99m DTPA Aer...

Lung scan is an accurate and noninvasive tool for evaluating the distribution of lung perfusion. We present a rare case total absence perfusion on to right with two contralateral defects due severe occlusion pulmonary artery, as well segmental arteries in left young female woman diagnosed Takayasu Arteritis. highlight similarities findings between arteritis disease thromboembolic importance car...
